Description

Description: TECHNICAL FIELD The present invention relates to a thermal transfer method.

[Prior Art] Conventionally, there has been known a thermal transfer method in which an original image corresponding to an image of an original is formed as a hole in a stencil original to form an original, and the image of the original is thermally transferred to recording paper. The thermal transfer device used in such a thermal transfer method has a structure in which a rotating case is rotatably mounted on the apparatus main body, a pressing plate having a cushion material is provided on the apparatus main body, and a flash means is provided on the rotating case. Has become. The flash means has a structure in which a discharge lamp is provided in the light source chamber of the rotating case, one surface of the light source room (the surface facing the pressing plate) is opened, and transparent glass is attached to this opening. The cushioning material is used to uniformly and uniformly adhere the original plate for stencil or the like to the original and the recording paper.

When performing thermal transfer using such a thermal transfer device, the stencil plate is attached to the outer surface of the transparent glass, and the original is placed on the cushioning material of the pressing plate. The original is created by sandwiching the original between the original and the cushion material, and in this state, flashing a discharge lamp to form holes in the stencil original corresponding to the image of the original. Then, in the case where the original transfer is performed to the recording paper using the original, the ink is squeezed out from the ink tube in which the hot-melt type ink is sealed and applied to another sheet, and the sheet is overlaid on the inner surface of the original. Attached to the transparent glass, the recording paper was placed on the cushion of the pressing plate, and the rotating case was rotated as described above to arrange the recording paper between the original plate and the cushion material so that they were brought into close contact with each other. By flashing the discharge lamp in this state, a copy image corresponding to the original image is transferred to the recording paper. in this case,
Since the entire surface of the recording paper, the original plate, and the sheet on which the ink is applied adheres more uniformly to the cushion material, a copied image having a uniform density can be obtained.

[Problems to be Solved by the Invention] In such a thermal transfer method, a stencil master or a prepared master is attached to the rotating case side during the preparation of the master and the main transfer, and the rotating case is attached to the apparatus body. In this method, the original or the recording paper is sandwiched between the original on the rotating case side and the cushion material on the apparatus main body side to perform copying. In the main transfer, the original image can be transferred only to flat recording paper or the like. That is, the original plate is attached to the transparent glass on the rotating case side,
Since the recording paper is placed on the cushioning material on the main body of the apparatus, if the recording medium has an arcuate curved surface during transfer, the original does not fit into the transfer surface of the recording medium, so it should be flat. Can only be transcribed. Therefore, for example, it is not possible to copy on a curved surface such as an arc surface or a bent surface such as a bat, a vase, and a pencil. Cannot copy.

An object of the present invention is that it is not necessary to sandwich a recording medium between an original and a cushion material, a simple operation of pressing an original or the like can be easily copied, and is not limited to a flat surface.
It is an object of the present invention to provide a thermal transfer method capable of favorably copying a curved surface such as an arc surface or a curved surface of a bat, a vase, a pencil or the like.

[Means for Solving the Problems] The thermal transfer method of the present invention includes the following steps.

a) a step of preparing a manuscript in which an image is formed on a recording material with a material that absorbs light and generates heat, wherein the material that absorbs light and generates heat includes carbon used for a lead such as a pencil; Ink containing carbon used in ink pens, ink applied to ink sheets for printers, toner for electrostatic copying machines, etc.
Materials called so-called carbon, carbon black, graphite, etc., or a mixture of these materials and other materials are optimal, but not limited thereto.

The recording medium may be anything that is generally called recording paper, and a plastic film is also suitable.

As a method of forming an image, in addition to handwriting with a writing instrument, mechanical drawing by CAD (Computer Aided Design), or the like, printing may be performed using an ink sheet for a printer. A typical example of the latter is thermal printing. Further, a copy of an image by an electrostatic copying method is also included.

b) a light source room having a light transmitting window on at least one surface, a light source lamp disposed in the light source room, a transparent body provided in the light transmitting window, and fixedly or detachably attached to an outer surface of the transparent body. Preparing a thermal transfer device having a given translucent elastic sheet, and holding means for holding the original in a stacked state on the outer surface side of the elastic sheet, wherein the heat transfer device is entirely or translucently opaque. In the case of the light-transmitting case, the light-transmitting window is formed as an opening. However, in the case of a light-transmitting case, the opening need not be formed. As the transparent body, other than glass, plastic such as acrylic resin can be used. Further, as will be understood from embodiments of the present invention described later, the transparent body is not limited to a flat body, but may be a curved body. In addition, a translucent elastic sheet looks like white foam, like urethane foam or foamed polyester,
Any material may be used as long as it has a light-transmitting property such that the back side is faint when viewed through light. Of course, the higher the translucency, the more effective the practice of the present invention. The elastic sheet may be fixed to the outer surface of the transparent body by means such as adhesion or screwing, or may be detachably attached by an attachment mechanism provided in the apparatus body.
The holding means is for laminating an original plate to be described later on the outer surface side of the transparent body directly or via a reinforcing sheet or the like.

c) a step of holding the thin sheet on the outer surface side of the elastic sheet of the thermal transfer device by the holding means. Here, the thin sheet is preferably a transparent resin sheet such as polypropylene, but the material is not limited thereto. Also, paper based paper such as paraffin paper may be used.

d) The heat transfer device is placed on the document, and the other surface of the thin sheet is pressed against and adhered to the image forming surface of the document. E) forming a master by forming a transfer image of the image of the original on a sheet; e) a light reflecting layer at least in a portion facing the mounting region of the master; and a hot melt ink layer on the outer side of the thermal transfer device. Step of covering with an arranged ink sheet, wherein the light reflection layer may be formed on the ink sheet or may be formed on a sheet separate from the ink sheet. In the case where the original is separated from the ink sheet, it is effective that the ink sheet is joined to the engaging means so as to move together with the engaging means when inserting and removing the original. In addition, the ink sheet may be attached while the original plate is held,
An ink sheet may be attached first, and an original may be inserted between the elastic sheet and the ink sheet.
In this case, the ink sheet may be covered by being attached to a thermal transfer device.However, the ink sheet may be rolled in advance and attached to the thermal transfer device, and then transported by an appropriate feeding mechanism so as to cover the original mounting region. May be. Furthermore, the ink sheet may be simply placed so as to cover the recording medium without being attached to the thermal transfer device.

f) With the original plate, the light reflecting layer and the ink sheet pressed against the recording medium via the transparent body of the thermal transfer device,
Flashing a light source lamp of the thermal transfer device to form a copy image corresponding to the original image on the recording medium.

[Operation] According to the thermal transfer method of the present invention, when performing copying,
There is no need to sandwich the recording medium between the original and the elastic sheet. Just by pressing the original against the recording medium, the original is brought into close contact with the recording medium and the like by the translucent elastic sheet fixed to the transparent body. be able to. Therefore, copying can be performed easily, and the recording medium is not limited to flat recording paper, but may be a curved surface such as a bat, a vase, a pencil, or another curved surface, a curved surface such as a curved surface, or a binding medium such as a notebook. A clear copy can also be made near the side edge.

Trigger circuit 27 is intended to include boosting transformer, safety in a state in which the contact S _c1 is closed switch S _c, boosts the voltage charged when the discharge switch S _b is closed to the flash capacitor C ₁ To flash the discharge lamp 13.

Next, a case will be described in which the original plate 24 is created and transferred to the recording medium 23 by the thermal transfer device 1 configured as described above.

When preparing the master 24, first, the holder 3 is removed from the lower part of the apparatus main body 2 as shown in FIGS. In this state, the operating levers 6, 6 of the apparatus main body 2 are operated to push down the holding members 15, 15 as shown in FIG.
The thin sheet 19 is set on the lower surface side of the transparent body 17 provided below the light source room 12. That is, the operation button of the operation lever 6
When the pusher 6a is pushed from the outside, the turning arm 6b turns around the pin 6c in the direction of the arrow X, and the tip of the turning arm 6b is a holding member.
The respective contact portions 15c, 15c of 15 are pushed down against the coil spring 20. Then, the holding member 15 has the guide portions 15b, 1 at both ends thereof.
5b is guided by the guide grooves 5a, 5a of the lower case 5, and moves downward, and the locking portion 15a at the lower end thereof is pushed downward from the cushion material 17a provided below the transparent body 17.
In this state, the locking portion 15a of the holding member 15 and the cushion material 17a
And insert the thin sheet 19 between them. In this case thin sheet
If the flexible sheet 19 is difficult to insert, the transparent sheet having substantially the same outer shape as the thin sheet 19 may be bonded to the thin sheet 19 as a reinforcing sheet and inserted. At this time, it is preferable that the reinforcing sheet is inserted toward the cushion material 17a side, but the reinforcing sheet may be formed in a rod shape as shown in FIG. The sheet may be directed to either side. When the pressing of the operation lever 6 is released, each holding member 15 is pulled up by the coil spring 20 as shown in FIG.
The edge of the thin sheet 19 through the cushioning material 17a
Press directly against the edge of 7. As a result, the thin sheet 19 is attached to the entire lower surface of the transparent body 17 by the elasticity of the cushion member 17a, as shown in FIG. That is, since the cushion material 17a is formed so that its size is smaller than the distance between the locking portions 15a, 15a, the locking portions 15a, 1
5a, the edge of the thin sheet 19 is pressed directly against the edge of the transparent body 17 and held, and is pulled in from the lower surface of the thin sheet 19. After the thin sheet 19 has been attached in this way, as shown in FIG.
Place on 22. In this case, the document 22 is placed on a flat placing table 28 such as a desk. In this state, when the device main body 2 is pressed from above, as shown in FIG.
17a is compressed, and the lower surface of the thin sheet 19 is uniformly pressed against the image forming surface of the document 22 and is brought into close contact therewith. In this case, the locking portion 15 pulled in from the lower surface of the thin sheet 19
a, 15a until it comes in contact with the original 22 and
a is compressed, and the thin sheet 19 is uniformly brought into close contact with the document 22.
Thus, the thin sheet sheet 19 comes into close contact with the document, the safety switch S _c is closed to contact S _c1 running. This allows
The original 24 can be created.

Then, set the power switch S _a provided on the upper surface of the apparatus main body 2 to the ON state. Then, the contact S _a as shown in FIG. 8 is closed, charging is started to flash capacitor C _1, the voltage V ₀ increases with charging of the flash capacitor C _1, which together with the constant voltage detection circuit 25 input voltages V ₁ is the contact L _a of the relay L becomes a predetermined value is opened, and the charging of the flash capacitor C ₁ is stopped, at the same time the light emitting diode
10 lights up. Lighting of the light emitting diode 10 indicates that flash preparation is completed. In this state, when closing the discharge switch S _b, the voltage accumulated in the flash capacitor C ₁ is supplied to the trigger circuit 27, a high voltage is applied to the trigger electrode of the discharge stripe 13, a discharge lamp
13 emits a strong flash.

As shown in FIG. 10, when the discharge lamp 13 emits flash light, the light beam is irradiated on the document 22 through the transparent body 17, cushion material 17a, and thin sheet 19 provided at the lower part of the light source chamber 12, as shown in FIG. You. Then, since the document 22 is elastically adhered to the lower surface of the thin sheet 19 by the cushioning material 17a, the upper layer portion of the ink image 22a provided by printing or copying on the surface of the document 22 (that is, contained in the ink) Carbon or the like) is transferred to the lower surface of the thin sheet 19 as a transfer ink image (copy image) 19a as shown in FIG.
This is because the material such as carbon contained in the ink image 22a absorbs light rays and generates heat, and this heat causes the lower surface of the thin sheet 19 and the binder that binds the carbon toner contained in the ink image 22a to melt and adhere to each other. It is due to the effect of being done. As a result, the ink image 22a of the original 22 is
Is faithfully and clearly transferred to the original 24.

Next, the transfer ink image 19 transferred by using the original
The case where a is completely transferred to the recording medium 23 will be described.

In this case, first, the reels 21, 21 around which the ink sheet 18 is wound are stored in the respective reel storage portions 3 b, 3 b of the holder 3, and the holder 3 is mounted on the lower portion of the apparatus main body 2.
That is, each end of the ink sheet 18 is
1, and the intermediate ink sheet 18 is placed under the holder 3, as shown in FIG.
21 and 21 pass through the side of the holder 3 and the reel storage section
3b, inserted from above 3b, and each shaft portion 21a of the reel 21, 21 ...
Are rotatably supported by the shaft supporting portions 3f. In this state,
The holder 3 is made to correspond to the lower portion of the apparatus main body 2, and the hooks 3 c provided on the front and rear of the holder 3 are engaged with the locking recesses 11 c on the apparatus main body 2 side. Thereby, the holder 3 is mounted on the lower part of the apparatus main body 2. When the holder 3 is mounted in this manner, as shown in FIG. 6, the original plate 24 held on the lower surface side of the transparent body 17 of the light source chamber 12 projects downward from the opening 3a of the holder 3, and The ink sheet 18 is stretched. The apparatus body 2 on which the ink sheet 18 is stretched in this way is
As shown in FIG. 12, it is arranged on the recording medium 23 on the mounting table 28. In this state, the device body 2 is pushed down from above,
As shown in FIG. 13, each locking portion 15a, 15a of the holding members 15, 15
Is pressed against the recording medium 23 on the mounting table 28. Then, the cushion material 17a is compressed, so that the original plate 24 is
8 elastically adheres to the upper surface. At the same time, the ink sheet 18 comes into close contact with the recording medium 23. Also in this case,
Safety switch S _c is closed to contact S _c1 actuated. As a result, transfer to the recording medium 23 becomes possible.

In this state, when transferring to the recording medium 23,
As with the original creation described above first sets the power supply switch S _a to the copying position II. This will start charging the flash capacitor C _1, the charging of the flash capacitor C ₁ is completed, the light emitting diode 10 is turned on. In this case, the voltages V ₁ and V ₂ increase as the charging voltage V ₀ increases, and have a relationship of V ₁ > V ₂ . Therefore, the constant voltage detection circuit 25 operates later when it is connected to the original preparation position I than when it is connected to the copy position II. In other words, a long charging time for the flash capacitor C ₁ than when towards the case of the power supply switch S _a set mask fabrication position I is set to the copying position II, are charged to a high voltage. Therefore, at the copying position II, the discharging switch S _b
Is closed, the discharge lamp 13 emits a weaker flash than at the time of preparation of the master.

In this way, when the discharge lamp 13 flashes, the light beam is applied to the ink sheet 18 thereunder through the master 24 as shown in FIG. When the light beam irradiates the master 24 in this manner, the master 24 has an ink image 22a of the original 22 on its lower surface.
Since the transfer ink image 19a formed by transferring a part of the transfer ink image 19a is provided, the light of the transfer ink image 19a does not transmit, and the transfer ink image 19a contains carbon having good heat absorption. The portion of the transfer ink image 19a absorbs light rays and has heat. Since the other portions transmit light, they do not have heat. Therefore, the original 24
Light transmitted through a portion other than the transfer ink image 19a of the original sheet 24 is reflected by the light reflection layer 18b of the ink sheet 18, so that the ink sheet 18 in this portion does not have heat, but The part absorbs the irradiated light rays and has heat. Then, this heat is transmitted to the heat-sensitive ink layer 18c via the light reflection layer 18b and the base film 18a of the ink sheet 18, and only the heat-sensitive ink layer 18c in this portion is melted, and the fused portion 18d is shown in FIG. Is thermally transferred to the lower recording medium 23 as described above. As a result, a copy image 18d of the color of the heat-sensitive ink layer 18c corresponding to the transfer ink image 19a of the
The main transfer is assured and clear. Note that another recording medium 23
When the transfer is performed again, one of the reels 21, 21 exposed from the holder 3 is turned with a finger or the like, and the ink sheet 18 necessary for one transfer is newly drawn out below the original 24. The discharge lamp 13 may be set and flashed in the same manner as described above. By repeating this, any number of sheets can be transferred, and furthermore, it can be easily transferred to a recording medium joined with a note or the like. In this case, a thin leaf sheet
When the transfer ink image 19a transferred to 19 is thermally transferred to recording paper via a normal ink sheet, the transfer ink image
Since 19a is transferred little by little to the ink sheet, it cannot be used just by transferring it to several sheets of recording paper. However, in the present invention, the ink sheet 18 in which the light reflection layer 18b made of a metal deposition layer is formed on the upper surface of the ink sheet is used, and the transfer ink image 19a of the thin sheet 19 is in contact with the light reflection layer 18b. Therefore, it is not transferred at all to the light reflection layer 18b, and can be transferred to an extremely large number of recording media.

In the present embodiment, the holder 3 on which the ink sheet 18 is mounted can be replaced without removing the holder 3 from the apparatus main body 2. That is, when the operating levers 6 and 6 are operated in the state shown in FIG. 6, the holding member 15 is pushed downward similarly to the case of FIG. 4, but at this time, the original plate 24 is pressed onto the cushion material 17a. The stopper 15a is separated from the original 24 and the ink sheet 18 is lifted up.
As shown in the figure, the locking portion 15a and the ink sheet 18 are largely separated from the cushion material 17a. Therefore, while taking out the original plate 2 previously mounted on the apparatus main body 2,
Another master 2 can be inserted.

In the thermal transfer apparatus 1 described above, the transfer ink image 19a of the original plate image 24 can be fully transferred to a curved surface such as a vase 30, as shown in FIG. That is, in this case,
As in the case of the main transfer to the recording medium 23 described above, the original 24
Is pressed against the outer peripheral surface of the vase 30 with the ink sheet stretched underneath. Then, cushion material 17a
Is compressed along the arc surface of the vase 30 and conforms, so that the ink sheet 18 adheres to the original plate 24 accordingly,
It also adheres to the outer surface of the vase 30. Therefore, if the discharge lamp 13 is caused to flash in this state, the light beam is irradiated onto the ink sheet 18 through the master 24 as in the case of the main transfer described above, so that the ink sheet corresponding to the transfer ink image 19a of the master 24 is formed. The 18 thermal ink layers 18c are melted, and the melted portions 18d are permanently transferred to the outer peripheral surface of the vase 30. It is preferable that the image thus transferred is coated with a transparent coating material so that the image does not disappear even if the outer peripheral surface of the vase 30 is rubbed. The curved surface on which the main transfer is performed is not limited to the vase 30, but may be a bat, a ball, an arc surface such as a golf club head, a spherical surface,
And a combination surface thereof, or a curved surface such as a hexagonal pencil or the like. Therefore, in a bound sheet such as a notebook, a clear transfer can be performed also near the bound side edge. This also applies to the preparation of the master, and it is possible to clearly copy the image near the bound side edge of a notebook, a book, or the like, and it is also possible to satisfactorily create the master 24.

The present invention is not limited to the above-described embodiment, and can be variously modified.

For example, the ink sheet 18 may be one in which a light reflection layer 18b and a heat-sensitive ink layer 18c are sequentially laminated on the lower surface of a base film 18a, or only the light reflection layer 18b may be formed as a separate sheet. FIG. 17 shows the latter embodiment. In this example, the light reflecting layer 18b is provided on the lower surface of the transparent resin sheet 32 having substantially the same outer shape as the original 24 (the rear surface opposite to the original 24), and is adhered to the original 24 at one side edge thereof by the adhesive tape 33. The transparent resin sheet 32 is bonded. In this case, the transparent resin sheet
Numeral 32 is also used as a reinforcing sheet, and is integrated with the original plate 24 so that the original plate 24 faces the transparent body 17 side and the apparatus body 2
Attached to. According to this method, the light reflecting layer 18b is
Since only the same area as 4 is required, ink sheet 1
8 can be cheaper. Further, the transparent resin sheet 32 having the light reflection layer 18b on one surface as described above may be fixed to the locking portions 15a, 15a of the holding member 15 by bonding or the like. Reflective layer 18b is all original 2
4 can be used in common, so it is even cheaper.

Furthermore, the cushion material 17a is formed into an outer shape of the same size as the original plate 24, and is superimposed on the original plate 24, and in some cases, in a temporarily bonded state, is inserted from between the transparent body 17 and the locking portions 15a, 15a,
You may make it hold | maintain with the locking parts 15a and 15a. In this case, the cushion material 17a serves as a reinforcing sheet when the original plate 24 is inserted. Of course, the cushion member 17a may be detachably attached by another attachment mechanism (not shown).

Further, the transparent body 17 is not limited to a flat one, and the outer surface may be formed in advance in a concave or convex curved shape in accordance with the shape of the recording medium. The apparatus main body 2 may be configured to be detachable.

As described above, the ink sheet 18 includes the light reflection layer 18b.
May be separately provided, but in either case, a structure in which the device is directly attached to the apparatus main body 2 without the intervention of the holder 3 is also possible. In addition, if a feed mechanism for the ink sheet 18 is provided in the apparatus main body 2, it is sufficient to move the ink sheet 18 by the feed mechanism without removing the ink sheet 18 from the apparatus main body 2 even when preparing an original. Can be Further, although a little inefficient, the ink sheet 18 (with or without the light reflection layer 18b) can be singly placed on the recording medium 23 without being attached to the apparatus main body 2. Alternatively, the original 24 attached to the apparatus main body 2 may be pressed onto the non-recording member 23.

Further, in the above embodiment, the flash energy of the discharge lamp 13 was made different between the time of making the original and the time of copying.However, in an actual test, the same flash energy was sufficient to achieve the purpose. As an example, the switching circuit can be eliminated.

[Effects of the Invention] As described above in detail, according to the thermal transfer method of the present invention, it is not necessary to sandwich the recording medium between the original and the elastic sheet when performing copying, and the original is recorded on the recording medium. The original can be brought into close contact with the recording paper or the like by the light-transmitting elastic sheet fixed to the transparent body simply by pressing the original. Therefore, it can be easily copied, and the recording medium is not limited to flat recording paper, but may be a bat, a vase, a curved surface such as a curved surface such as a pencil, or a bound paper such as a notebook. Clear copies can also be made near the bound side edges.
